The constellation Cepheus as it may be seen by the naked eye. Alderamin, also known as Alpha Cephei, is the brightest star in the constellation, with an apparent magnitude of 2.51. [5] Gamma Cephei, also known as Errai, is the second-brightest star in the constellation, with an apparent magnitude of 3.21. [6]
Alpha Cephei (α Cephei, abbreviated Alpha Cep, α Cep), officially named Alderamin / æ l ˈ d ɛr ə m ɪ n /, [10] [11] is a second magnitude star in the constellation of Cepheus near the northern pole. The star is relatively close to Earth at 49 light years (ly) and drifting closer with a heliocentric radial velocity of about −16 km/s.
Gamma Cephei (γ Cephei, abbreviated Gamma Cep, γ Cep) is a binary star system approximately 45 light-years away in the northern constellation of Cepheus.The primary (designated Gamma Cephei A, officially named Errai / ɛ ˈ r eɪ. iː /, the traditional name of the system) [11] [12] is a stellar class K1 orange giant or subgiant star; it has a red dwarf companion (Gamma Cephei B).
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Mu Cephei (Latinized from μ Cephei, abbreviated Mu Cep or μ Cep), also known as Herschel's Garnet Star, Erakis, or HD 206936, is a red supergiant or hypergiant [4] [7] star in the constellation Cepheus. It appears garnet red and is located at the edge of the IC 1396 nebula.
Xi Cephei (ξ Cephei, abbreviated Xi Cep, ξ Cep) is a multiple star system in the constellation of Cepheus.It is approximately 86 light-years from Earth. [6]It consists of two binary stars, designated Xi Cephei A and B, together with a more distant companion, Xi Cephei C.
Nu Cephei (ν Cephei) is a class A2, fourth-magnitude blue supergiant star in the constellation Cepheus, visible to the naked eye. It is a white pulsating α Cygni variable star located about 4,700 light-years from Earth. ν Cephei is a member of the Cepheus OB2 stellar association, [5] which includes stars such as μ Cephei and VV Cephei.
